Good news for those hoping to get an early start to their Labor Day weekends: normal service on Metro’s Red Line is now back up and running.

It’s a quick turnaround for the line, which was damaged in an overnight derailment. According to a Washington Metropolitan Area Transit Authority press release, two sets of wheels on a nonpassenger train came off the tracks outside Rhode Island Avenue station, damaging signal cables and other equipment. The accident forced the closure of four stations from Fort Totten to NoMA-Gallaudet, prolonging morning commutes, but WMATA reports that no residual delays are expected (at least until 10p.m., when it will begin scheduled repairs on the line).

The cause of the derailment is still under investigation.
